Description
Cyanophora paradoxa. The chloroplasts of Cyanophora, unlike chloroplasts of most algae and plants, have a cell wall containing peptidoglycan. This is thought to be left over from the endosymbiotic origin of the organelle from cyanobacteria. Each culture contains enough material for a class of 30 students. This culture requires a low light level (50 to 100 foot-candles of fluorescent light or fluorescent light from the ceiling). Optimal medium: EREM. Optimum growth temperature: 22° C.
